Application filed December 14, 1923.

This invention relates to Washing machines and its object is to provide improved means for securing the gudgeons or trunnion pieces to the rotory wooden drum or cylinder of such machines.

Heretotore it has been customary to secure the gudgeons or trunnion pieces to the woodon heads of the drum by means of bolts passing through the heads and gudgeons. This arrangement causes considerable trouble due to the fact that after a few months use the wood of the heads becomes softened to such an extent that when attempt is made to tighten the nuts on the bolts the bolts will turn in the soft wood thus making it difficult or impossible to firmly tighten the bolts and causing more or less mutilation of the heads with resulting leaking. In some cases circular metal plates or washers are placed on the inside of the drum and the fastening bolts passed through such plates and through the heads and trunnion pieces, but such arrangement is also more or less unsatisfactory because such plates must be made comparatively small to fit within the radial ribs on the inside of the drum, the result being that the bolts for securing the gudgeons must be brought toward the center of the head to such an extent that they do not support the gudgeons on the head as satisfactorily as when the bolts are placed near the outer periphery of the heads. By my improved construction I provide a plurality of short plates or washers, preferably curved which are of such length as to be placed between the ribs in the drum and positioned near the outer edge of the heads and secured thereto by bolts passing through the heads and gudgeons. The result is that the trunnion pieces or gudgeons are secured to the heads near the outer edge thereof and as the plates or washers on the inside may be made with squared holes to fit the squared heads of the bolts it follows that the bolts may be tightened to any extent desired without any danger of turning in the softened wood.

My improved construction is illustrated in the accompanying drawings forming a part of this specification and in which 1 is a longitudinal sectional view through one end of a washing machine drum, this view showing one of the trunnions for supporting the drum and the gear wheel secured thereto for rotating the drum;

Serial No. 680,778.

Fig. 2 is a sectional view substantially on the line 2-2 of Fig. 1;

Fig. 3 is a detailed sectional view showini particularly one of the "fastening bolts ex tending through the head of the drum from the inside to the outsidethereof and F 1g. d is an enlarged plan view o1 one end of one of the plates or washers used on the inside of the drum.

Referring to the drawings in'detail, the numeral 10 indicates the rotating drum out a washing machine in the end of which a head 11 is suitably secured. A. plurality of ribs 12 extend from the outer wall of the drum 1O inwardly as is customary in constructions of this kind. To support the drum for rotary movement, suitable gudgeons or trunnion pieces 13 are attached. to each head oi the drum. The construction at each end of the drum is substantially the same and illustrz tion and description of the construction at one end only will sutlice. A trunnion 13 secured to the trunnion piece 13 is supported in a suitable bearing 14 and the usual gear wheel 13 -is secured to the trunnion for rotating the drum.

It will be note-d that the trunnion piece or gudgeon 13 is made of such size as to extend outwardly almost to the outer edge of the head 11, which arrangement is possible by reason of my improved construction.

In order that the bolts used for holding the trunnion piece to the head will be inca= pable of turning when tightening the nuts, and in order that such bolts may be placed as nearly as possible to the outer edge of the head, I provide a series of plates or washers 15 arranged within the drum. These plates or washers 15 are made of such length that they may be arranged between two of the inwardly projecting ribs 12 ot' the drum. These plates are preferably made curved, and at each end are provided with a I suitable opening 15 for receiving fastening bolts such as 16, these openings 15 prefer ably being square or of other angular shape to receive squared heads 16 on the bolts whereby rotation of the bolts is prevented when the nuts are tightened thereon. Preterably each of the plates 15 is provided with two bolt receiving openings 1? one at each end and the bolts 16 are passed through these openings and through the material of the head and through suitable openings or noise in the trunnion piece 13. Asshown in the drawings a plate or washer 1 5 is placed in each alternate space between the ribs 12, but it is of course apparent that a plate of this kind may if desired be used between each two ribs of the drum.

From the foregoing it will be apparent that I provide a construction in which the bolts for holding the trunnion pieces to the drum may be tightened whenever desired without danger of the same turning in the soft wood of the head. This follows from the fact that the squared heads of the bolts engage the similarly formed openings in the plates 15 and also from the fact that at least two bolts pass through each'plate 15 so that the plates are incapable'oi movement when the bolts are tightened. Furthermore the bolts 'may be placed near the outer edgeof the head so that they'possess the maximum holding power for securing the trunnion pieces to the heads. A simple and eliiclent arrangement 15 therefore produced. Having thus described my invention what I claim as new and desire to be secured by ra'lityof ribs extending from the outer wall thereof inwardly and also having a head se cured tothe druin with a trunnion-piece attached to the head the improvement which comprises a plurality of plates arranged on the inside of said head, each or" said plates being arranged'between two of said ribs and positioned near the outer edge of the head and fastening bolts passing through said plates and trunnion-piece and through the materialof the head.

In testimony whereof I hereunto afli-X my STEWART- C. GOEY.
